Mr Revels described yesterday how he let another driver pick up a fare after both were accidentally dispatched to the same job in autumn 2010.

He told how, some time later, he was parked in Fountainbridge when Mr Aryaei Nekoo stopped and tried to start a fight. Questioned by prosecutor Douglas Fairley QC, Mr Revels agreed he had only given a description of the man to police and not his name – but had recognised Mr Aryaei Nekoo in a newspaper.
